6 Claims. (Cl. 24-205) My invention relates to sliders for slide fasrelation. The slider body has upper and lower teners. The expression slide fastener as used wings with flat surfaces. Such a slider may be in the art, refers to a fastening device having formed from non-metallic material, suchaspyroxcooperating rows of small closely spaced fastener ylin, by cutting out the Y-shaped channel from to be closed, and having a slider mounted on the sticking them together. elements for quickly engaging and disengaging In Fig. 2 a fabric stip such as the cloth ribbon them as it moves from one end to the other of the 12 is attached at its ends to the opposite ends of fastener. the slider and extends over the upper fiat surface.

My invention aims particularly to improve the Preferably the ends of the strip are adhesively 10 slider construction in respect tothe pull device secured to the slider.

5 fastener elements in and out of intermeshing 1. A slider for slide fasteners comprising a non-metallic channeled body member having smooth outer surfaces, and a flexible fabric strip adhesively secured to the said body member and constructed so as to lie flat against an outer surface of said body member or be lifted away from such surface when used for operating the slider.

2. A slider for slide fasteners comprising a channeled body member having an upper surface and a flexible flat fabric strip secured to said body member and adapted to be folded flat against said upper surface, said upper surface being entirely flat except for the flexible fabric strip.

3. A slider for slide fasteners comprising a channeled body member made of non-metallic material, and a flexible fabric strip adhesively secured to said channeled body member.

4. A slider for slide fasteners comprising a channeled body member having a flat upper surface, a fabric strip secured to opposite ends of said slider body and extending over said flat surface, a pull tab attached to said fabric strip and slidable from one end to the other of the slider.

5. A sliderfor slide fasteners comprising a channeled body member of non-metallic plastic material, a flexible pull member having at least one of its ends embedded in said bodymember for securing the same thereto. 7 p

6. A slider for slide fasteners comprising a channeled body member of plastic material and having a flat upper surface, and a cloth ribbon having its ends secured to said flat upper surface and extending upwardly therefrom in thef'orm of a loop functioning as a pull member, and being foldable to be flat against said upper surface.
